Package spore is a native Go port of the SPOrE overlap-removal and
compaction providers targeting ELK.js 0.12.0 behavior.
The implementation is translated from these EPL-2.0 sources at ELK commit

- the relevant geometry methods in ElkMath, KVector, and Utils
The exact official elkjs 0.12.0 bundle is the behavioral oracle. No code
from elkrs or OpenJDK is used by this package.

Package-Level Functions (total 2)
Register installs both providers and captures the registry for ELK's
optional underlyingLayoutAlgorithm delegation.
RegisterOptions installs the metadata generated from SPOrE.melk in ELK
0.8.1. Shared core options are registered only when absent.
